New Democratic PartyNDPFrench Nouveau Parti DémocratiqueCanadian democratic socialist political party favouring a mixed public-private economy, broadened social benefits, and an internationalist foreign policy.

The NDP grew out of the Co-operative Commonwealth Federation (CCF), which was founded in 1933 as Canada’s first political party representing workers and small farmers. The CCF secured power in Saskatchewan in 1944, by which time it had developed a national organization, run candidates in all sections of the country, and polled an appreciable popular vote. However, it was never large enough to become the official opposition, nor did it hold the balance of power between the country’s two major parties, the Liberal Party of Canada and the Progressive Conservative Party. In 1956 most of Canada’s labour groups united in the Canadian Labour Congress, which in August 1961 formed the New Democratic Party, incorporating the CCF but welding a stronger working arrangement with organized labour. (The provincial party in Saskatchewan retained the CCF name until 1967.) The NDP was able to form governments in Saskatchewan, Manitoba, and British Columbia intermittently from the 1940s to the 1990s, in the Yukon Territory from the 1980s, and in Ontario, Canada’s largest and wealthiest province, in the 1990s. At the national level, however, it enjoyed only scattered success, its support peaking in the 1988 election, when it won 43 seats in the House of Commons. The NDP suffered a dramatic decline in the following election, winning only nine seats, and, though it rebounded somewhat in subsequent elections, it generally polled little more than 10 percent of the vote. In the elections of 2004 and 2006, however, with support for the Liberals dropping, the NDP fared better, winning 19 and 29 seats, respectively, in the House of Commons. This upward trend continued in the 2008 election, in which another 8 seats were added, bringing the NDP total to 37.

The NDP’s longtime base has been among the farmers of Manitoba and Saskatchewan and the urban workers of British Columbia and Ontario. With the rise of the Reform Party (later the Canadian Alliance and the Conservative Party of Canada) in the late 1980s, support for the NDP in the west declined somewhat. During the mid-1990s and early 21st century the NDP gained in popularity in the Atlantic provinces, particularly Nova Scotia, where it polled 30 percent in the 2006 federal election.
